Name of the variable in the generated code for the corresponding modeling element, specified as a character vector.

データ型: char

Name of the data type that is represented in Simulink for the corresponding modeling element, specified as a character vector.

データ型: char

Indication that the type qualifier contains const, specified as a numeric or logical 1 (true) or 0 (false). If you cannot change the value of the variable during execution, the variable is preceded by the const keyword as the type qualifier in the generated code.

  • 1 — The type qualifier contains const.

  • 0 — The type qualifier does not contain const.

データ型: logical

Indication that the type qualifier contains volatile, specified as a numeric or logical 1 (true) or 0 (false). If the compiler cannot apply optimizations to the variable because its value can change due to external sources, the variable is preceded by the volatile keyword as the type qualifier in the generated code.

  • 1 — The type qualifier contains volatile.

  • 0 — The type qualifier does not contain volatile.

データ型: logical

List of union members, specified as a vector of coder.descriptor.types.AggregateElement objects.
